the supercharger wasn't really invented/widespread till 3078, so that will be a problem. Similarly compact fusion engines were released till around that time as well...not to mention the compacts are heavier than XL, so instead of adding space you are actually removing it.
The cudgel is using MASC to increase his speed and not TSM
Speed doesn't generally increase as weight drops, TSM still requires you to run your mech hot though (according to the pnp rules you need to over heat by 7 points, and speed and targeting generally decrease as the heat levels go up).
The only way to make a Charger faster is to then add the MASC which also has a chance of burning out during use.
Ok... about half your post is demonstrably wrong...
From the supercharger entry: "While an unusual if experimental add-on for centuries
, the technology achieved a mainstream level of acceptance and refinement during the Word of Blake Jihad, with manufacturers within both the Inner Sphere and Clan-space regularly producing superchargers from 3078 on."
So not unavailable just unusual but commonplace
The compact fusion engine is stated to be half
the size of a standard engine but 50% heavier
so I am freeing space at the cost of weight with that, but I think the Endo Steel and Ferro-Fibrous armor more then make up for that. And I'm not sure when it becomes available as the wiki only says that it's "A relatively new concept, few base variant 'Mechs utilize this engine." and then goes on to mention two 'Mechs that do use it standard which were released in 3069 and 3068 respectively... since those are only some of the first to use it standard
there is no indication of when it first becomes available as an optional
upgrade. Unless you have another source of data? If you do I could really
use some supplemental info. Regardless the LX engine the Charger-3K has standard is double
the size for half
the weight, so just switching to a standard engine might work anyway.
entry clearly states it uses TSM.
If you have a larger engine but less for it to move then you can move it faster, simple physics applies after all. I am also aware of the heat requirements for TSM but between the 5 ER medium lasers and the jump jets I should be fine, to say nothing of the flamers or the supercharger. Also since TSM makes you go faster
when it activates I think you can ignore the slowing effects of heat as being already compensated for. As for the drop in targeting... hopefully I'm close enough to punch them by the time that becomes and issue.
As Matt said, you're depending on technologies that don't exist at this point. The Charger's engine can't get any lighter then it is beyond slowing it down which is defeating the point of this plan. You could use MASC ofr short sprinting bursts but it's risky and won't improve your base speed. The safe (ie, not booby-trapped) Triple-Strength Myomer doesn't exist at this point either beyond a handful of prototypes.
Also, the Charger-3K wouldn't be widely available outside the Combine military at this point; it was a cutting edge and moderately secret machine. The Cudgel also doesn't exist at this point.
If running fast and punching people is what you're after, a modified Ostroc or Ostol could do the trick with the availble tech. Given time, I can whip something up.
I've addressed the first few statements here above and I said I might have to use the TSM that still reacts to the gas, but it only
reacts to a certain type
of gas so it's not like it a normal battlefield condition and I figured I risk it.
The 3K was deployed as early as 3039, that's 10 years since it was confirmed seen in action
for the manufacturer who is stated to engage in black market sales
to sell a shipment or two off. I know the Cudgel doesn't exist yet, that was just the first example I found of an 80 ton 'Mech that moved 86km/s standard and had TSM, it was mentioned as a way to show how I worked out my numbers for the speeds reached.
The punching came up because the Charger is known for doing so, so I ran with it. I mostly just enjoy the concept of an Assault class scout 'Mech which is what the Charger was originally designed for. It allows for a scout that is far less dependent on cover and one which can be more daring in where it goes because it doesn't have to worry about being killed in one hit from the Atlas around the corner. Once the battle proper has been joined and scouting becomes less important it can perform flanking (and counter-flanking) maneuvers and work on running down smaller and weaker enemy
scouts (which is the reason for the ER lasers instead of the pulse lasers it comes with, more range for damaging light and medium scout 'Mechs, allowing him to catch up faster and without having to chase them as far away from the engagement site). This design is based less around fighting other Assault 'Mechs and more around scouting highly dangerous areas or those with limited mobility, where standard scouts would be at risk, and harassing enemy Heavies and Assaults while still being able to catch and kill any Light or Medium that's foolish enough to come too close. Does that make sense?
